I do not have a Netflix account, but I started my 1 month free trial just for my 3DS.

I was watching some Angry Beavers and some thing about Prehistoric creatures and then I fell asleep.

The quality isn't bad, but I expected it to be a little better. I have no problem with the screen size, and the sound is good.

I'm not a huge fan of movies, and have soooo many movies I need to watch because people always ask if I've seen them. Going to keep using it for the rest of my trial. I'll decided whether I want to keep going with it after that.

Im watching Full Metal Alchemist on it now.
It's pretty smooth. A little slow though and there are some load times. I think this is a good sign of things to come on the 3DS. I was extremely close to actually selling the unit on Craigslist till this. For those who are still wondering, the movies are NOT in 3D at this time. As a matter of fact, even the top screen on my 3DS is not in full use. It seems to be running in a mode more compatible to the NDS right now.

What do you mean? The size?
I think that depends on the tv show or movie. I watched X-men: Evolution and Charmed and they had black borders on the left and right but then I switched to the show Dollhouse and it was wider and took up the top screen.
